What type of audits do IAA inspectors conduct?

B is the correct choice because IAA (Irish Aviation Authority) inspectors perform regular audit inspections and tests to ensure compliance with aviation regulations and standards. These audits are vital for maintaining safety and operational integrity in the aviation sector. They focus on assessing whether airlines and airports adhere to regulatory requirements, best practices, and safety protocols.

The regular audit inspections help identify potential areas of risk or non-compliance, allowing organizations to address these issues proactively. Regular audits can cover various aspects, including operational procedures, safety measures, and maintenance protocols, ensuring that both airlines and airports can operate safely and efficiently.

In contrast, financial audits focus specifically on the financial records of an organization, which is outside the scope of IAA inspectors. Environmental audits would examine the ecological impact of airport operations, while marketing audits would assess promotional strategies and effectiveness. These areas, while important, do not fall under the routine inspections and tests conducted by IAA inspectors in their role of ensuring safety and compliance within the aviation industry.
